The main subject matter of the invention is a device (1) for setting a turbomachine propeller blade (2), characterised in that it comprises a first disc (3) and a second disc (4) respectively provided with first (5) and second (6) coupling means, the first (3) and second (4) discs being coaxial, means of tilting (9, 10, 11, 12) at least one of the first (3) and second (4) discs with respect to the other, the device (1) being configured so that, during a tilting of at least one of the first (3) and second (4) discs with respect to the other, the coupling distance (D) of said at least one blade (2) on the first (3) and second (4) discs remains constant, bringing about the rotation of said at least one blade (2). |
